Tabs have been creeping in to eLua's source files, sometimes representing
2 characters, sometimes 8. This patch replaces them all with the appropriate
number of spaces, according to the context.
This only fixes files that were written specifically for eLua, not the
manufacturers' SDK source files that were simply imported into the tree.
- added some more documentation (not yet done)
- alternate uarts can be selected (boot mode defaults to console uarts)
- renamed "remote" references to "rpc" (may as well keep the original name)
- switch default error handler to luaL_error (presumably wasn't available for
old 4.x LuaRPC)
- tweaks to exception handling to make things more consistent (hopefully)
- disabled by default (enable on a target-by-target basis) so it shouldn't
cause much breakage for non-rpc users
- some modifications to the binary chunk reader which should allow reading of
chunks encoded on various platforms (with certain limitations like lualong
can't read float lua bytecode, one must generate lualong bytecode from a float
lua)
- other misc changes.
